These pieces of hardware allow this bracket: http://www.thingiverse.com/thing:62443 to be more firmly attached to a MakerGear M2 printer by securing it to this tool holder: http://www.thingiverse.com/thing:198825 I drilled a hole in the tool holder and webcam bracket, cut a piece of 6-32 all thread rod to length which was routed through the printed sleeve and used nylon lined stop washers to connect that half of the assembly. I drilled small pilot holes in the webcam bracket and tool holder faces and used torx head screws I had laying around to further stabilize the assembly on the right side by attaching the printed brace part. I also used double-sided tape to stabilize the webcam bracket. Note: This was a very quick and dirty design and print. It works, but is not geometrically perfect and requires manual modification of the printed parts involved. Your mileage and visual satisfaction may vary, ;)
